2.13. PR Bitstream Compression and Encryption ( Intel® Arria® 10 and Intel® Cyclone® 10 GX Designs)

You can compress and encrypt the base bitstream and the PR bitstream for your Intel® Arria® 10 and Intel® Cyclone® 10 GX PR project using options available in the Intel® Quartus® Prime software.

Compress the base and PR programming bitstreams independently, based on your design requirements. When encrypting only the base image, specify whether or not to encrypt the PR images. The following guidelines apply to PR bitstream compression and encryption:

  • You can encrypt the base and PR image independently. You can use a non-volatile encryption key for the base image, and a volatile encryption key for the PR image.

  • Refer to Clock-To-Data Ratio for Bitstream Encryption and Compression to ensure the correct Clock-to-Data (CD) ratio setting for encryption or compression.

Enable enhanced decompression by turning on the Enable enhanced decompression option when specifying the parameters in the IP Catalog or Platform Designer parameter editors.

Note: You cannot use enhanced decompression together with encryption simultaneously. Enhanced decompression is only available with the Partial Reconfiguration Controller Intel® Arria® 10 /Cyclone 10 FPGA IP.
